FEEDING MECHANISM FOR CLOTH-FINISHING MACHINES.

SPECIFICATION forming part of Letters Patent No. 380,139, dated March27,1888.

Application filed November 27, 1886. Serial No. 220,092. (No model} Toall whom it may concern:

Be it known that I, J OSEPH J. SOHOLFIELD, a citizen of the UnitedStates, residing at Providence, in the State of Rhode Island, haveinvented a new and useful Improvement in Feeding Mechanism forCloth-Finishing Machines, of which the following isa specification. Myinvention consists in the combination of an endless spur-belt with apivotally-held spur-roller or a pivotally-held roller provided with afriction-surface adapted to deliver the edge of the web to the spurs ofthe beltin an approximately-true line, and in the combination of theendless spur-belt, the pivotallyheld spur-roller, and guide-rollersadapted to hold the edge of the web in contact with the spurs of theendless belt, and in the improved combination of the spur-roller withapivoted temple-frame, as hereinafter fully set forth.

Figure 1 represents a vertical section taken in the line w x of Fig. 2.Fig. 2 is. a plan view of my improvement as applied to feed a web ofcloth to the drying-cylinder of aclothdrying machine. Fig. 3 is anelevation of the feeding-in end of the mechanism. Fig. 4 represents anenlarged detail section taken transversely of the belt and thebelt-carrier in the line as m of Fig. 1. Fig. 5 represents an enlargedtransverse section of the endless belt, showing a modified form of theholding-spurs. Fig. 6 is an enlarged vertical section of the vpivotally-held spur-roller and its supporting.

bracket.

Figs. 7 and 8 are detail views showing the combination of supplementalspurrollers with the endless spur-belt. Fig. 9 is a top view of apivoted spur-roller operated by means of aregulatingmechanism',which'serves to dispense a portion of the driving-power ofthe machine to move the roller upon its pivot,

as required, the drivingpulley being removed. Fig. 10 is a plan viewshowing the regulating mechanism,-t-he spur-roller and the ratchet-wheeland driving-pulley being removed. Fig. llis an elevation of the pivotedspur-roller and the regulating mechanism. Fig. 12 is a detail plan viewshowing the arrangement of the spur-belt with the pivoted spur-roller,which is operated by the regulating mechanism.

In the accompanying drawings, A A represent a portion of the oppositeheads of the peripheries of which are provided with the attached bandsof card-clothing B, which are adapted'to hold the'web in its outspreadconditionwhile being dried.

- Near the surface of the card-clothing bands B B is placed thecard-covered roller O,which extends from side to side of the machine, soas to embrace the full width of the web which is to be fed to the same.The roller 0 is loosely jou-rnaled in the bearings a a of the frame D,whichis provided with the two parallel rods EE, upon which are placedthe oppositelyinclined adjustable belt-carrier frames F F, which areprovided with the slotted hubs b b and the set-screws c 0, thuspermitting the carriers to be set and firmly held at. any desired degreeof inclination to the axis of the web.

Upon the inner side of the belt-carrier frame F, and at its oppositeends, are placed the flat scored pulleys G G, which turn loosely uponthe studs H H, and upon the scored faces of the pulleys GG is placed theendless spur-belt I, which is also supported at its working upperportion by means of the flange J of the carrier-frame, which flange isprovided with an upwardly-turned rim,.K, serving to support the edge ofthe belt against the transversely-directed drawing-strain of the web.Over the spurs of the belt I, and in close proximity thereto, so as toleave about the thickness of the edge portion of the web between them,is placed the plate L, which serves to hold the edge portion of the webfirmly against the spurs of the belt, or the spurrollersM M, set atright angles to the axis of the spur-belt, as shown in Figs. 7 and 8,may be employed for this purpose, the plates L shown in Fig. 7 beingomitted in Fig. 8. The

spurs d d of the flexible belt I are beveled outwardly, and also bent inthe same direction, as shown in Fig.4, in order to firmly hold upon theedge portion of the web; but in some cases the outward bending may beomitted, as shown in Fig. 5. The, edge of the web may be guided upon thespurs of the belt I by means of one or more pivo'tallyheldroller-temples, N N, which, by automatically turning upon their pivotswhen the edge of the web is being.

drawn through the said temples, will serve to keep the edge of the webin an approximately being held in the pivoted frame R of the temple. Theperiphery of the collar 1' is preferably roughened, so as to causefriction when the edge of the web comes in contact therewith, and thecorner j of the frame R is beveled, thus forming with the periphery ofthe collar 42 a wedge-formed groove for the reception of the edge of theweb when running at its proper outward position. the roller Q which liesoutside of a line joining the extremities of the pivot-screws e e ismade longer than the inner portion of the same,

so that when the edge portion of the web is inclined to run off of theroller Q the said roller and its frame R will turn upon the pivots e e,thus causing the edge of the web to again run onto the roller, and bythis means preserving a nearly-uniform running-line for the edge of theweb.

The roller-temple is to be so pivoted and set that the edge of the webwill run in the wedgeshaped groove formed between the periphery of thecollar '5 and the frame B, so that upon any excess in outward movementof the edge of the web the increased friction produced by the narrowedportion of the wedge-shaped groove upon the edge of the web'will causethe roller and its pivoted frame to turn upon the pivots, so as to causea slight backward movement of the said edge, thus tending to preservethe edge of the web in an approximately true running-line for guidanceonto the spurs of the belt. The projecting stop 1" upon the rear of theroller-frame R serves to prevent excessive pivotal movement in thedirection of the running web. The frame D is also provided with thetie-rods S and T, and upon the rod T, between the adjustable collars ss, are placed the card-covered rollers U U, which revolve loosely uponthe rod T and serve to press the web against the adjacent ends of thespurs of the endless belts I I. The web in its passage through. themachine passes from a loose pile over the rod S, thence through theroller-temples N N and under the rod T and rollers U U onto the inclinedendless spurbelts I I, which serve to stretch the web widthwise, andthence under the card-covered roller 0 and onto the heads A A of thedrying-cylinder. The pivotally-held temple-roller, in-

stead of being operated by means of the tractive force of the web, maybe operated by means of any suitable regulating mechanism, if preferred.

The web when passing through the pivoted temples N N should be in acomparatively The portion of loose condition widthwise, for the reasonthat the strain upon the temples caused by the widthwise tension of theweb tends to interfere with their proper pivotal action. The belt I, asshown in the accompanying drawings, is preferably made of leather orother flexible material, the spurs d d being inserted therein, as incard-clothing.

The pivoted spur-roller may be operated by means of a regulatingmechanism which dlspenses a portion'of the driving-power of the machineto effect the required change in the angular position of thesaidroller,as shown1n Figs. 9, 10, 11, and 12, in which A is a bedplateprovided with the hubs B O D. Upon the stud E, which enters the hub Band is secured thereto, is loosely placed the vibrating lever F, one endof which is provided with the oppositely-arranged catches G G, which,when in action, are held against the teeth of the ratchet-wheel H bymeans of the springs I".

To the vibrating lever F at the point J 1s pivoted the catch-guard K, towhich is plvoted the rod L, which is loosely held in the guide M at theopposite end of the lever F, and which is provided with the stud-pin N,which enters and loosely fits the circular slot 0 at one end of thedetector-lever P, the said lever P being pivoted to the hub O of thebaseplate, so that a vibrating movement can be imparted to the lever Fby means of the cocentric Q and connecting-rod R without imparting acorresponding movement to the connected detector-lever, the saideccentric being secured to a driving-pulley, V, which is loosely heldupon the stud W, secured to the hub D of the bed-plate. The spur-rollerQ is held to revolve upon a screw-stud, h, projecting at one side of ahead, S, which is secured to the ratchet-wheel H, so as to movetherewith, and is flanked on either side by the guiding-studs T T, whichserve to guide the edge portion of the web properly around a portion ofthe periphery of the said spur-roller Q, in order that a change in theangular position of the head S will cause the spur-roll to move the edgeof the web, as required.

The combination of the mechanism above described with the spur-belt isshown in Fig. 12, in which the movement of the detector-1ever outwardagainst the action of the spring U by the pressure of the edge of theweb against the pin X of the detector-lever will cause a tiltingmovement of the pivoted guard K, which is attached to the vibratinglever F, thus allowing one of the catches, G, to act upon the teeth ofthe wheel H to cause the required change in the angular position of thespurroller Q to cause the reverse movement of the edge of the web uponthe spur-belt, and when the edge of the web has a tendency to runinwardly the detector-lever will be caused to follow up the said edgethrough the resilient action of the spring U, so that the pivoted guardK will be caused to tilt in the opposite direction, whereby the oppositecatch, G, will be caused to engage with the teeth of the ratchet rangedat right angles to the axis of the spur-p belt for holding the edge ofthe web upon the 15 spurs of the belt, substantially as described.

. 3. The combination, with the obliquely-set spur-belt, of thepivotally-held temple-roller adapted to deliver the edge of the web tothe spurs of the belt in an approximately true line and the intermediateroller for pressing 20 the edge portion of the web against the spurs ofthe belt, substantially as described.

-- 4. The combination, with the pivoted temple-roller frame providedwith the wedgeshaped groove for applying friction to the edge 25 oftheweb tocanse the proper guidance of the same, of the temple-roller forguiding the edge of the web, substantially as described.
